Summary:
1. `--version` never makes it to infer.py
2. `--project_root` should always be set by infer.ml invocation
3. there is no need to set `--project_root` to the same value again

Summary:
Right now, taint gets lost if it flows into a constructor or procedure whose implementation is missing.
Since the core Java (e.g., String) and Android classes (e.g, Intent) are among these, this is bad.
We could handle this by writing a bunch of models instead, but that would be a lot of work (plus we may still miss cases).

Summary:
Merging the results directories of targets on buck projects involved creating symbolic links into buck-out.
The bulk of files are .attr files: one per procedure. Creating these links can be a bottleneck, and the merge phase can be slower than the analysis phases on projects with many procedures.
This diff introduces multilinks to speed up merge.
A multilink is a file `multilink.txt` containing a sequence of paths
```
path/to/file1.ext
path/to/file2.ext
...
```
A multilink file is a compact way to represent a link for each entry.
This diff creates a multilink file for each `attributes/dir` directory, instead of one symbolic link for each file.

Summary: The frontend replaces global variables that are constant with their values as a quick hack to improve the precision of the analysis. This should apply to `constexpr` too.

Summary: This diff simplifies the workflow of creating the procedure descriptions. Instead of creating the all procedure descriptions in a first step and translating the method bodies afterwards, it is simpler to translate to do the two in one step.

Summary: Fix the resolution of symbolic links. The previous version did not work if the path itself was not a symbolic link, but there was a symbolic link somewhere up in the path tree. For example: `path/to/file` where `file` is not a symbolic link, but `to` is a symbolic link.

Summary:
Fix an issue where, when `-reactive` mode is used, files captured in the first second are not considered modified, and are not analyzed. This happens because file timestamps are used, and the resolution is one second.
Change the front-ends to change the timestamp of the directory where artifacts are created, so that the timestamps are 1 second in the future.
Small reactive commands such as the following now analyze correctly:
rm -rf infer-out && infer --reactive -- clang -c test.c

Summary:
Declared and defined procedure attributes are now saved in different files (hashed_name.decl.attr and hashname.attr).
We always try to load using the filename of defined procedure attributes first,
and fall back to loading the file for declared ones if it does not exist.
The logic for replacing an existing file stays the same, with one extra thing:
when a file for a defined attribute is written, the one for the declared one
is deleted if it exists.
At the end of a capture, either a declared or a defined file exist, but not both.
The reason for this change is that when captures of different subprojects are
merged together, it can happen that a link gets created to a declared attributes
file even though a defined one exists, so the body of the procedure will not be analyzed.
After this diff, both links will be created, and the defined one will be loaded
by the back-end.
